In the post, the first on his site, Whitemire said the Muppets, for him, “are not just a job, or a career, or even a passion. They are a calling, an urgent, undeniable, impossible to resist way of life.”

According to his post, there were two issues executives and Disney had with him. The issues were not specified.

“Through a new business representative, I have offered multiple remedies to their two stated issues which had never been mentioned to me prior to that phone call,” he wrote. “I wish that we could have sat down, looked each other in the eye, and discussed what was on their minds before they took such a drastic action.

“I have remained silent the last nine months in hopes that the Disney company might reverse their course. Doing what is best for the Muppets is the lens through which all my interactions have been filtered. Given the opportunity I remain willing to do whatever is required to remedy their concerns because I feel my continued involvement with the characters is in the best interest of the Muppets.”

A Muppet Studio spokeswoman said on Monday that Whitmire was being replaced by Matt Vogel.

Whitmire, who referred to Henson as his hero in the blog, apologized to fans.

“I just want you all to know that I am sorry if I have disappointed any of you at any point throughout our journey, and to let everyone know that I am devastated to have failed in my duty to my hero.”

In a statement to Time, a Muppet Studio spokesperson said, “The Muppets Studio thanks Steve for his tremendous contributions to Kermit the Frog and The Muppets franchise. We wish him well in his future endeavors.”
